[T4.1.3] Problems using ajax with Tapestry
Hi I have problem with my ajax code. I try
to run the code in my tapestry app, but
when I read the results in firebug from my calls, I get an
empty string "" from the tapestry servlet,
when I indeed expect to see a well formed html
page. I have tried to run the url that I call
directly through the browser, which turns out to
run just fine, but it seems that when i use the
prototype Ajax.Updater it will not load the html content??
My script looks like this:
function getHTML() {
dojo.log.info("Running getHTML");
var url = '<span jwcid="@Insert" value="ognl:url" raw="ognl:true"/>';
var myAjax = new Ajax.Updater(
'<span jwcid="@Insert" value="ognl:returnid"/>',
url,
{
method: 'get',
onFailure: reportError,
asynchronous: false,
evalScripts: true,
onComplete: showResponse
});
}
I have verified that the url that is inserted into the url variable
is valid, and the script also replaces the placeholder that is
correctly inserted. But as told above, it seems that the
tapestry servlet returns an empty string "" from the call.
Is there a filter or something that prevents tapestry from
responding properly to the Ajax.Updater calls? Is this a
configuration issue for me? I am pretty sure people
have been using this technique before :-)
I know I could do something similar with the built in
tapestry components, but I have to build some specially
tailored ajaxstuff here to make my customers happy.... :-)

Andy, thanks soooo much, that did the trick. I fixed the prototype.js file not
to include the X-Prototype-Version in the header, and swoooosh the file appeared
as it should. I cannot thank you enough
Best wishes

Ok - i haven't really used prototype in Tapestry, but i took a quick look
at PrototypeResponseContributorImpl in org.apache.tapestry.services.impl
and it looks like that ResponseBuilder overrides the default one if it finds
X-Prototype-Version
in the request headers...
So, assuming that prototype adds that by default, it may explain things...
Is it possible to configure your call not to include that header?

Yes, I get the full page as I expect it to be loadede through the ajax call.
I can even see - when I try to load through the AjaxUploader - that the page I
want to load is rendered. I log out a message in the target page
prepareForRender method, that assures me that in fact tapestry creates the page
on the server side. I just do not get the page returned to the client.

But, what happens when you GET that url directly? Do you see anything returned?
